Cost?

On the web site www.rapidwelding.com they have it for 3780 British Pounds and the torch for 498 British Pounds. At today's rates that would make it $6500 to $7000. But I believe that is for the cold wire feed setup. On the www.weldreality.com website they depict a base unit which provides the hot current onto the .045 wire. I can't find any European references for a possible package price.

Looks like the setup we had at the boiler shop I worked at back in the late 70's early 80's. We were welding boiler tubes to the tube sheets after they were rolled. Our unit was hooked up to a Hobart Cyber-TIG machine, we used .023 wire in ours and it produced some of the nicest looking welds. I'm not sure if it's exactly the same as that unit but it looks very similar.

The unit I was using back then was designed in the early 60's by a company known as Griscom Russell which was bought out in the mid 60's by Baldwin, Lyman & Hamilton in Philadelphia PA. The reason I know this is my step-dad worked for Griscom Russell and the boiler company I was working for was owned by a former Griscom Russel engineer, who bought the buildings and much of the equipment that Griscom Russell had at the time.

I'm not sure if Griscom Russell had patented the setup or not, but I remember using it on several 9th stage heaters for Ohio Power in Niles OH. I do know that removing the tubes that were welded to the tube sheets was nothing less than a cast iron b***h!!!

Both cold and hot wire delivery systems are used in mechanized welding operations. Cold wire is common, hot wire is less common.

Manual cold wire GTA is fairly common and can produce a high production rate compared to manual GTA. The torch mounted wire guide may work for certain, repetive weld joints but is not as flexible as the seperated torch and wire system.

Also, It is important to note that any of the commonly avaliable wire delivery systems can control wire pulsation but provide no means to sync the weld current pulsation to that wire pulsation.

I looked into this company and went to their free workshop in Philadelphia in Dec 2009. They had a lecture followed by hands on demos and practice in their shop. Tip Tig USA is located in the old Philadelphia Navy yard.

They had about 20 attendees ranging from engineers to welders.
The shop had 2 machines set up for practice. One was a red one which they had to do some cut and paste wiring with the remote plugs to get everything to work. This red machine was set up for stainless using .035" wire.

The other machine was hooked up to a Dynasty 350 and only required the menu to set the machine to 2T mode of operation. The Tip Tig machine used the standard 14 pin plug on the Dynasty.

I was very impressed at how even a novice found the set up easy to use and everyone was running smooth beads after 1 minute of pactice.

The machine is a modified hot wire system and imparts a special back and forth motion to the wire as it is fed into the arc.
Machine uses standard mig wire spools and the torch is special in that it uses a hand switch and wire guide.

I showed the instructor how get into the Dynasty menu and was surprised to see that their machine only had about 650 arc starts and less than 75 hours

The Dynasty machine was set up for carbon steel pipe welding in the 2G position and everyone (even a bozo like me) was able to walk the cup easily after about a minute of practice. I have done a little tigging but never walked the cup before this.
